Nasal irrigation efficiently attenuates SARS-CoV-2 Omicron infection, transmission and lung injury in the Syrian hamster model.
Article in iScience, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Recently, a new variant lineage of SARS-CoV-2, namely Omicron, became the dominant global circulating strain. The multiple antigenic mutations of Omicron largely decrease the efficiency of current vaccines and neutralizing antibodies, which highlights the need for more potent and reachable medical countermeasures. Here, we hypothesize that direct viral clearance by nasal irrigation might be a convenient and alternative option, and perform proof-of-concept experiments in the Syrian hamster model. Interestingly, Omicron shows a different dynamic in the changes of viral RNA, viral titers, and proinflammatory cytokines in nasal rinsing samples when compared with the prototype. Meanwhile, the levels of viral load and proinflammatory cytokines in nasal rinsing samples can indicate the severity of lung injury. Of note, daily nasal irrigation efficiently attenuates inflammation and lung injury in Omicron-infected hamsters by decreasing the viral loads in the respiratory tract organs. Moreover, daily nasal irrigation effectively suppresses viral transmission by close contact.
